Arthroscopic Anterior Glenoid Bone Grafting for Shoulder Instability Using an Interconnected Suture Anchor Technique

Anterior bone grafting is an established and frequently used treatment option for recurrent anterior shoulder instability in combination with significant glenoid bone loss. Several open and arthroscopic fixation techniques have been presented to this field in recent years. Some of these techniques are associated with different peri- and postoperative problems or complications. Therefore, the technical gold standard for anterior bone grafting has not been determined, resulting in an ongoing evolvement of bone-grafting techniques. Arthroscopic, metal-free fixation procedures were introduced to the field bone grafting to overcome previous problems of screw fixation. These metal-free techniques frequently include surgically challenging transglenoidal drilling and are placing anterior soft tissues and neurovascular structures at risk. We therefore present an arthroscopic anterior, PEEK (polyether ether ketone)–anchor based, interconnecting bone-grafting technique bypassing previous challenges to restore the anterior glenoid bone stock with adequate positioning and fixation of the bone graft.
